In millions of newspapers across the United States there is a word game called
Jumble. The object of this game is to solve a riddle, but in order to find the
letters that appear in the answer it is necessary to unscramble four words. Your
task is to write a program that can unscramble words.
The input contains four parts:
1. a dictionary, which consists of at least one and at most 100 words, one
2. a line containing XXXXXX, which signals the end of the dictionary;
3. one or more scrambled `words' that you must unscramble, each on a line by
4. another line containing XXXXXX, which signals the end of the file.
All words, including both dictionary words and scrambled words, consist only
of lowercase English letters and will be at least one and at most six characters
long. (Note that the sentinel XXXXXX contains uppercase X's.) The dictionary
is not necessarily in sorted order, but each word in the dictionary is unique.
For each scrambled word in the input, output an alphabetical list of all dictionary
words that can be formed by rearranging the letters in the scrambled word. Each
word in this list must appear on a line by itself. If the list is empty (because
no dictionary words can be formed), output the line ``NOT A VALID WORD"
instead. In either case, output a line containing six asterisks to signal the
end of the list.
NOT A VALID WORD
